Vanessa-Rude and Belittling

I found the company and called them requesting New installation. I was required to make payment which I did immediately upon receipt of quotation and banking details. I had to wait for the installation date as they hadn't received proof of payment. When calling to enquire about a date scheduled for installation it was then when I spoke to Vanessa who did not listen at all to me but kept intejecting as I spoke but expected me to keep quiet and listen to her. Because I needed the service I obeyed and later spoke to Irene who spoke well and with respect...I did tell her of my unhappy call earlier with Vanessa her colleague and she apologised on her behalf. After the service there were things I still needed along with the certification and upon calling to my dismay I spoke once again to Vanessa and as she had been before,still disrespectful and careless to my needs as a customer. I did let her know her behavior towards me is unnecessary and she went on to tell me that it is me that needs her not vice versa,so whether I continue or not with Cishumlilo it is me that will not receive certification as that was my biggest concern. Her rudeness helped me to realize that I will never again after certification use her company or even refer others to the company merely for her attitude
